The rear edge of the reinforced by an angle 11, see. Figs. 3, 6 and body member 1 is 7 which'is secured to the outside of the said body member.

nions '14, 14, of a rear end closure 15, the.

formed on suitable brackets 17 17Qsecured respectlvely to the top corners'of the metal plate, constituting the said end closure 15. The said; closure plate is in the present instance reinforced by a. metal strip 18 which extends around the edge side, as best illustrated in Figs. 3 and '7, and is further reinforced at its top edge by meansof'an angle. bar 19. The end closure 15, aswill bereadily understood',is adapted thereof at the out,-

to hinge upon the trunnions 14,14, and toswing outwardly of the body when, the latter is tilted upward at the front'in a manner to It will further be noted that the brackets 17 which include the be described hereinafter.

trunnions 14:, 14, are offset at the top so that the said trunnions lie within the edge of the body whereby when the body is in the normal horizontal position, there isa tendency of the rear end closure 15 to press against the edge of the body, this proper automatic closing of the end closure when. the body is returned from the tilted to the normal horizontal position and the proper engagement of the said end closure by the locking means, which will be described hereinafter.

.The body member under side thereof, one at each side of the center line, a pair of longitudinal beams 21, 21, in the present instance of' I-sec-tion, which beams form the sole support-and rein forcement of the body member 1 except as obtained through the forward end closure 2', the angle iron 45,' and the angle 11 which is secured at he rear edge of the said body member. This construction has been found extremely desirable by reason of the flexibility afforded the body, which accordingly conforms itself without undue; to which bodies of 1 has secured to the' construction insuring the thereto a pair of spaced straps 25 and 26, each of which, as best illustrated in Fig. 9, extends rearwardly of the blocks to which they are secured and take the form of an eye 27. Each of the straps 26 also extends forwardly of the blocks and downwardly to the frame 23, as best shown in Fig. to which the said strap is secured, thereby reinforcing the block and preventing a tendency of the latter to give rearwardly when the body is tilted. Secured to the under side of each of the longitudinal beams 21, 21, is a strap 28 which is adapted to lie between the straps 25 and 26, as clearly shown in Figs. 5 and 9, and which also has an eye 29 formed at one end which aligns with the eyes 27, 27, of the straps 25 and 26 and forms with the latter a bearing for a hinge pin or bolt 31 which secures the body to the frame of the vehicle and constitutes a pivot upon which the body swings. The hinge elements 28 are secured to the body in such position that the body is substantially balanced about the said pivot pin 31, although as will be apparent, the entire weight of the body when the latter is in the normal horizontal position falls upon the blocks 22, 22, and not upon the said pivot pin.

The forward ends of the beams 21. 21, nor mally rest upon or abut the top of a cross beam 32 which extends across the side beams 1 23, 23, of the vehicle, as best illustrated in Fig. 4. A function of this cross piece 32, aside from establishing a firm seat for the body when the latter is in the normal position, is to constitute an element of a lock ing means which not only retains the body firmly fixed at its forward end to the vehicle frame and thereby prevents the tilting of the body except when desired, but also prcvents any relative movement between the body and the vehicle frame when the vehicle is in motion.

As best illustrated in Figs. 3 and 4, the angle 8 and the plate 9 before mentioned are apertured and adapted to receive a vertical stem which at the bottom takes the form of a hook 34, this hook being adapted in one position of the stem to underlie the upper flange of the cross piece 32 which latter in the present instance is of I-section. The upper end of the stem 33 has pivotally secured thereto above the angle 8 an operating lever 35 which is so constructed that its inner end acts as a cam to elevate the stem 33 and bring the hook 34 tightly against the flange of the cross beam 32. As clearly illustrated in Figs. 3 and4, the said flange is turned downwardly at the point where it is engaged by the hook 34, thereby affording a tight grip for the hook. When the outer end of the lever 35 is elevated from the position shown in Figs. 3 and 4, or turned over to the opposite position, the

stem 33 is loosened, which permits the rotation of the stem 33 through an arc of which'carries the hook 34 from under the flange of the cross beam 32 and permits the elevation of forward end of the body. As illustrated in Fig. 4, the operating lever 35 has a hook-like projection 36 which when the lever is in the locking position engages the side of the angle 8 and prevents the turning of the operating lever 35 until it has first been elevated, and the arrangement of the aforesaid locking cam on the lever is such that considerable pressure is required for elerating the lever.

The cross piece 32 also constitutes an anchor for one end of a set of chains 37, 37.- the other end of each of which is secured to a resilient link 33, which latter are se cured to the body, in the present instance to the longitudinal beams 21, 21. The chains and links limit the upward movement of the forward end of the body and the resilient link constitutes a butter cushioning the, body when it is stopped by this limiting means.

Means is also provided. for normally looking the rear end closure in the closed position, said locking means comprising in the present instance a rectangular shaft 39 journaled in the beams 21. 21, as best illustrated in Fig, 6 and supporting a pair of hooks 4L 41.v which project through suitable slots 42, 42, in the angle iron 11 and are adapted to engage the lower edge of the rear closure 15. best illustrated in Fig. 3, thereby to retain this closure in the locked position. As illustrated in F gs. 6 and 10. each end of the shaft is held in a shouldered bushing 43. which latter find bear ngs in the said beams 21, 21, and the shaft 39 is prevented from longitudinal movement through the bushings by means of the hub portions 44 of the said hooks 41 which are secured to the said shaft by set screws 45, 45. These hubs abut the inner faces of the bushings 4343. and thereby prevent the aforesaid longitudinal movement of the shaft. The shaft also carries a collar 46 in which is secured one end of a spring 47, the other end of which is secured in a bracket 48 on the angle 11, as shown in Fig. 6, the spring 47 tending to rotate the shaft in a counter-clockwise direction, see Fig. 3. whereby the hooks 41, 41, are normally retained in an elevated locking position. Each of the hubs 44 of the said hooks 41 carries a downwardly extending arm 49 to which are respectively secured the ends of a connecting rod 51, said rod extending forwardly underneath the body. aS best illustrated in Figs. 2 and 3, and being secured to a slotted piece 52 at the center of the frame cross bar 24 by means of a chain 53, as illustrated in Figs. 3-and 5. The slot 54 of the element 52 is adapted to receive one of the links of the said chain 53 when the latter is 'in the perpendicular IOU position, but is so narrow as to prevent the passage of the horizontal links. This device accordingly constitutes a simple means for adjusting the length of the chain 53 to afford proper action of the locking device, as described hereinafter.

It will now be apparent that if the forward end of the body is elevated from the position shown in Fig. 3, there will be a tendency owing to the disposition of centers and the point at which the chain 53 is secured to the frame to effect a rearward movement of the arms 49, 49. which results in a rotation of the shaft 39, and consequent downward movement of the hooks etl and release of the rear closure 15. This release is accomplished automatically in the tilting of the body. Vhen the body is returned .to the normal position, however, the rear closure 15 swings downwardly and the hooks are released so that they are permitted again to return to the locking position. In this return movement. the aforedescribed position of the trunnions 14 which support the rear closure assures a movement of the closure to a position bearing tightly againstthe rear edges of the body, which in turn assures the return of the hooks ll. 41 to the locking position.
